ok, then let me refraise the question...
what is the highest shot you could use with a DPI kit with all stock internals and stock fuel injectors? And would you guys recommend the NX kit? Simplicity of install of a DPI kit (any harder than the nozzle kit?)
thanks!

Still 50 because you fuel pump will not give enough fuel after.
There is no need to upgrade injectors.
NX kits are the best as of now, IMO.
DPI is hard to install.
One stage colder plugs for every 50hp.
couple mm smaller gap would help as well for plugs

Yep... shot = whp. In some cases, a 75 shot could yield more than 75whp, generall its around the number of the shot depending on the PSI of the bottle, etc.
Dry shots do increase fuel for the last time... SHEESH. A dry kit bumps up fuel pressure to allow for more fuel flow through the injectors. If it didn't, you would run like 10:1 air/fuel on like a 50 shot, and a motor would be toast.
OP, I still don't know if the fuel pump is needed after 50. No one knows what the stock LPH of the fuel pump is... I still wanna know what it is. Still, a DSM pump is cheap and I know for a fact its around 190ish LPH.
DPI, I can see running 100 shot on stock internals/injectors/etc. After that, I would imagine pistons, the clutch, axles, etc. would start to get ornery and not like that much power going through them at once. DPI really isn't that hard of an install. Drill, stick 'em in and aim 'em right, and the rest is the same as any wet kit/dry kit.
And OP is right on how which plug and how to gap it.

I think you meant to say anything above 14:1 will make a toast out of the engine. 10:1 a/f is very rich.

I just woudn't risk to do it after 50 shot. and btw I think that DSM pumps are 255lph, pretty sure that I read that somewhere on dsmtrader.com

Dur, meant 17:1... wonder how I did that. 14:1 usually isn't too bad... might even get away with 15:1 if its only at the top end of your RPM. Another topic though.
Fairly sure my DSM pump was 190ish... I bought a 255LPH and saw an improvement in fuel flow, course my pump might just have been old.
